What's New in Hue

Cloudera Runtime 7.3.1.500 SP3:

Multi-Python Support for Hue

This release introduces Python 3.11 support for Hue across various operating systems. This enhancement ensures continued cluster stability by offering concurrent support for multiple Python versions, including Python 3.8 and Python 3.9. To access Python 3.11 for Hue, you must upgrade to Cloudera Manager 7.13.1.500 version.

You can now upgrade to newer Python versions without disrupting ongoing cluster operations, minimizing downtime, and ensuring a smooth transition.

Adopting Python 3.11 gives you access to adopt to the latest features, security patches, and performance improvements.

By default, Hue automatically selects the highest available Python version on the system. To set a specific lower version of Python, see How to configure a specific Python version for Hue.

Cloudera Runtime 7.3.1:

General availability (GA) of the SQL AI Assistant

Hue leverages the power of Large Language Models (LLM) to help you generate SQL queries from natural language prompts and also provides options to optimize, explain, and fix queries, promoting efficient and accurate practices for accessing and manipulating data. You can use several AI services and models such as OpenAI’s GPT service, Amazon Bedrock, and Azure’s OpenAI service to run the Hue SQL AI assistant.

To learn more about the supported models and services, limitations, and what data is shared with the LLMs, see About the Hue SQL AI Assistant.
To set up and enable the SQL AI Assistant, see About setting up the Hue SQL AI Assistant.
To see how to generate, edit, explain, optimize, and fix queries, see Starting the SQL AI Assistant in Hue.

Hue supports Python 3.9 on RHEL 8.8 and RHEL 8.10: Starting from the 7.3.1 release, Hue supports only Python 3.9 for RHEL 8.8 and RHEL 8.10. Before upgrading to Cloudera Runtime 7.3.1, you must install Python 3.9 on all the Hue servers, as Hue requires a Python 3.9 version and does not start without it. For information about migrating from Python 3.8 to Python 3.9, see Migrating from Python 3.8 to Python 3.9 on RHEL 8.8 or RHEl 8.10.
